Water safety is a race against time.
By the time a sample reaches a lab and gets processed, contaminated water has already been consumed. We change the timeline from days to minutes.

Colours follow the kit’s own detection chart. A simulation of that chart, not a live measurement.
Blue band is the control strip — only the lower pad reacts.

Five steps, one visit
The entire workflow runs where the water is.
Under a minute of hands-on work
Collect
Hands-onTake a small sample from any source.
Well, tap, tank or canal. The test travels to the water, so nothing has to be bottled and shipped anywhere.
Seconds · Sample vial
Add reagent
Hands-onAdd the enzyme reagent to the sample.
The enzymatic biomarkers arrive pre-measured — nothing to weigh, dilute or calibrate in the field.
Seconds · Reagent ampoule
Dip
Hands-onPlace the paper strip into the solution.
Paper does the rest. No incubator, no power supply, no laboratory bench.
Seconds · Test strip
Wait
UnattendedAllow about five minutes for the reaction.
Nothing to supervise. A laboratory would be starting a 48-72 hour incubation at this point.
About 5 minutes · Nothing — set it down
Compare
Hands-onRead the result against the colour chart.
Safe, boil before use, or contaminated — read by eye, by anyone, with no training.
